To all whom z't may concern.

Be it known that I, JOHN R. LowRnY, a citizen of the United States, residing at San Pedro, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hose Couplings, of which the following is a specification.

My invention relates to new and useful improvements in couplings of the type adaptable for use in connecting all kinds of hose, tubes or pipes, the principal objects of my invention being to generally improve upon and simplify the construction of the existing types of hose and pipe couplings, to prov1de a device that is relatively simple in structure, capable of being easily and cheaply produced and constructed so that it may be readily assembled or taken apart, to provide a device that can be easily connected or disconnected and producing a fluid tight joint when properly connected, and, further, to provide a coupling that will be Very effective in performing its intended functions.

Withl the foregoing and other objects in view, my invention consists in certain novel fe'atures of construction and arrangement of parts that will be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- The figure is a section taken lengthwise through the center of a coupling of my improved construction.

Referring by numerals to the accomp'anying drawings, 10 designates a tubular member to one end of which may be connected a hose or pipe such as 11 and the opposite end of said tube section being externally tapered toward its outer end as design'ated by 12, and the extreme outer end of said tapered portion being threaded as designated by 13 in order to receive an internally threaded ring or collar, 14.

Welded or shrunk on to the tubular member 1() at the inner end of the t'apered portion l2, is a collar 15 and arranged on the tapered portion of said tube and disposed between the collars 14 and 15, is a packing member or gasket 16v of rubber, leather or analogous compressible material.

Arranged to rotate freely u on the body of tubular member 10, imme iately to the rear of collar 15, is a sleeve 17 having a reduced portion 18 that is externally threaded, and rigidly xed in any suitable manner upon member 10 to the rear of this sleeve, is a retaining ring or collar 19.

The female member of the coupling comprises a sleeve 20 the outer end of which is adapted to he rigidly or otherwise connected in any suitable manner to a hose or tube such as 21 and the opposite end of said sleeve being internally threaded so as to receive the externally threaded member 18 of sleeve 17.

The intermediate portion 22 of sleeve 20 tapers slightly toward the outer end or the end that is connected to tubular member 21, and the internal tapered face of this portion 22 is adapted to bear directly upon the outer lface of packing member or gasket 16. When the threaded member 18 .is screwed into the end of the sleeve 22, the latter is drawn toward the sleeve 17, with the result that the packing member or gasket 16 is very tightly compressed without relative rotation between the tapered portions of the members l0 and 20, thereby producin a self-tightening fluid tight Joint an consequently accomplishing the desired result.

The sleeve 17 being free to rotate between the collars 15 'and 19, without unscrewing from sleeve 20, the connection between pipes 1l and 21 is practically a swiveled connection. When the packing member or gasket 16 becomes worn oinunft for service, it may be replaced by a new gasket by simply removing the ring or collar 14; but it will be obvious that the connection and disconnection of the parts referred to need involve only v'a compression of the packing 16, without rotation of contacting parts upon this packing; and that steam pressure upon the end of the packing must occasion such a transverse thickening thereof that the joint may be regarded 'as self-tighten- 1n gA hose or pipe coupling of my improved construction is comparatively simple, may be easily and quickly connected or disconnected without rotation of pipe l1 relatively to pipe 21, and is very effective in providing a practically swiveled and self-tightening fluid tight connection between the ends of hose sections, pipes and the like.

It will be readily understood that minor changesin the size, form and construction of the various parts of my improved pipe coupling may be made and substituted for those herein shown and described without on the tubular member against the packing departing from the spirit of my invention, member, an externally threaded sleeve the scope of which is set forth in the aploosely on the tubular member against the pended claim. sliding collar, `and an internally threaded 16 I I claim 'as my invention; j and tapered sleeve enclosing the packing A hose coupling comprising a tubular member and slidinz collar and adapted to member having an externally tapered end receive the externa ly threaded sleeve.
